It comes also with a 600 m water resistance, with screw-down crown and the diver extension with its bracelet.

But the bezel is bi-directional, so that it’s easier to adjust for use with the 24-hour GMT hand. This black & white bezel features numerals and scaling in contrasting colours. The bezel is made in ceramic ZrO2.

We, also should take into consideration that a diver’s watch always has a uni-directional rotating bezel to ensure that the diver can never accidentally decrease the displayed dive time.

Thus, this watch bezel is marked with a 24-hour scale instead of the 60-minute scale that you would need to see elapsed dive time.

Hence, this watch its not a 100% diver’s watch, even though it’s water-resistant to 600 meters and has a helium escape valve.

The point often overlooked is that Omega have removed the word “Professional” from the dial.

The Movement

–

In fact, another big novelty about this new Seamster Planet Ocean GMT is not about cosmetic, but about its inside. This escapement, used in the Master Co-Axial movements, were first introduced in early 2013. But the 2014 watches, from the same collection, comes also with these movements.

“Under the hood” this watch is powered by the self-winding (automatic) Omega calibre 8906 movement.

This movement runs at 25,200 vibrations per hour (3.5 Hertz) and provides a power reserve up to 60 hours.
